Anyone good at working out flight/planes numbers stuff like that

Basically all I know is my bestest friend gets into London Gatwick at 17:55pm according to his email to me a couple of days ago. He's flying from Thailand - but I don't know where from in Thailand and pretty sure he goes via somewhere. On the live baa arrivals - there are 3 flights - Inverness (can't be it!), Dalaman and Luxembourg - arriving at that time. Do you think it's likely he's gone via Dalaman?
